We redirect folks' My Documents folder to their own spot on the network file server. We noticed that the permissions over time have gotten a little too loose. Some people can get into others' network file folders. Without having to go to each and every folder on the network, is there a good way to do a mass edit?

Check that the users store is not inheriting permissions, copy if asked, and then remove every one except admins, that user, back up software accounts, and any manager that should have access. Their is scripts that may do all this but it looked time consuming for me to set up so I went user folder by user folder and was done in a hour.

The proper way is to fix the parent folder and make sure the "owner" permissions are set correctly.

That way from now on when you setup a new user it creates the folder with the correct permissions ( I am assuming you are creating the folder with ADuC).

Then for the existing users remove the permissions and reapply them with ADuC

I think you can just change \\server\users\username to something that doesn't work and just change it back. It will say "this folder already exists, do you want me to take control of it" Hit apply and it will add the user to the folder.
